Abstract
A method and apparatus for controlling the flow of a fluid past a device having a flow adjusting device comprising transmitting a temperature to a thermally reactive material having a coefficient of thermal expansion which produces a volume change in the thermally reactive material in response to a change in the temperature. The thermally reactive material is enclosed within a container having a movable portion which is moved in response to the volume change of the thermally reactive material and the movement of the movable portion is applied to actuate the flow adjusting device. The flow adjusting device may comprise a fluid propulsion device such as a fan or pump or a throttling device such as a throttling, check, or shuttle valve.
